Whether the air conditioner is on or not, rightCarThe impact of dynamics and economics is completely different. In terms of power, when the car starts from a standstill and accelerates to a certain speed, the car with air conditioning always has a feeling of sluggish response, which completely loses the refreshingness when the air conditioning is not used. But it doesn't feel it when driving at high speed. In terms of economy, the fuel consumption is significantly increased when air conditioning is used compared to when air conditioning is not used.
Then,Car air conditionerHow much power does it take? A household air conditioner driven by a motor only consumes 1 horsepower (about 0.735kW) for every 1 ton (3.5kN) of cooling capacity, while a car air conditioner needs every 1 ton of cooling capacity. It consumes 2 horsepower of engine power.This is because in order to save space in the car, the car air conditionerCondenserUsually the design is smaller, the condensing temperature is higher, and the ambient temperature is higher. In this way, in order to obtain the same cooling capacity, the car air conditioner must consume more power than the household air conditioner. Different models of automobile air conditioning systems consume different power values, and generally increase with the increase of cooling capacity, but the impact of air conditioning on automobile power is basically 10-15%. The specific performance is the acceleration performance of the car, that is, the acceleration time becomes longer, the climbing ability becomes smaller, and the maximum speed drops. However, when the vehicle speed is high, the power consumed by the air conditioner is much smaller than the power consumed by the air resistance, which causes the maximum speed of the car to drop little or even almost no effect.
What is the economic efficiency of using air-conditioned vehicles? Generally, the total weight of the air-conditioning system of a car is 30-50 kilograms, and the self-weight of the car has increased, which also increases the fuel consumption of the car. Small cars traveling in urban areas will travel 170 meters less per liter of gasoline and 40 meters less for medium-sized cars due to the increase in air-conditioning weight. Generally speaking, it has little effect.But if the air conditioning system is activated, becauseCompressorNeed to consume a certain amount of power, air conditioningFanIt also needs to work, which consumes a certain amount of engine power, and the mileage per liter of gasoline is much less. For example, when the temperature is around 30°C, turn on the air conditioning system and the car will travel at a speed of 32 kilometers per hour. If you travel 1000 meters less per liter of gasoline; if the speed is 80 kilometers per hour, you travel 840 meters less per liter of gasoline. However, the mileage per liter of gasoline is different for different models. If air conditioning is assumed to increase fuel consumption by 10%, a mini car with a fuel consumption of 6 liters per 100 kilometers will travel 1,520 meters less per liter of gasoline; a medium-sized car with a fuel consumption of 8 liters per 100 kilometers travels 1,100 meters less per liter of gasoline; A large car with a fuel consumption of 10 liters per 100 kilometers travels 910 meters less per liter of gasoline.
